Description

Technical Field

[0001] The present invention relates to a battery fine-disassembly device, in particular to a battery fine-disassembly system and a disassembly method. Background Art

[0002] The fine disassembly of battery cells is a key technology for the efficient recycling and resource reuse of waste batteries. Its core goal is to safely and environmentally extract valuable materials from batteries, such as positive and negative electrode materials, electrolytes, and diaphragms. During the disassembly process, pretreatment is required first to ensure the safety and operability of disassembly, and then the outer shell is cut by mechanical cutting to separate the outer shell from the movement, and the positive and negative electrode sheets and diaphragms in the core package are efficiently separated. After separation, the active materials and current collectors of the electrode sheets are separated separately for further recycling and purification.

[0003] During the recycling of existing batteries, a set of standardized equipment is used for battery recycling, that is, one set of equipment can only process one specification of battery. However, when processing other specifications of batteries, many structural parameters need to be changed, and the equipment needs to be adjusted significantly, which is relatively complex. Moreover, there are some special settings in the core packages of some batteries. For example, some batteries are not fully discharged, some batteries have multiple core packages, the starting positions of the diaphragms in some core packages are different, and the starting of the diaphragm in some core packages will wrap the negative electrode, resulting in various situations at each stage of battery disassembly. Often, when changing the battery specification, a large number of tests need to be carried out before disassembly, and repeated modifications are made during the disassembly process, which is relatively troublesome.

[0004] Therefore, this case aims to provide a battery fine-disassembly system and a disassembly method, which can provide highly adaptable structures at each stage of battery fine-disassembly to disassemble batteries with different specifications and different packaging methods, so as to ensure safety while fully utilizing all parts of the battery materials, with higher recycling efficiency, and the overall recycling process is smooth and stable without frequent updates.

[0015] The present invention also provides a battery disassembly method, which applies the above-mentioned battery precise disassembly system and includes the following steps: S1: Convey the battery into the detection machine table for discharge detection. The fully discharged battery waits for subsequent processing, and the incompletely discharged battery is conveyed back to the front-end position; S2: Clamp the fully discharged battery through the clamping member and move it to the position of the first positioning structure. Position the battery through the first positioning structure and the second positioning structure. Cut off the outer shell on one side of the battery through the first cutting member. Similarly, cut off the outer shell on the other side of the battery in the same way to expose the core package of the battery; S3: Fix the cut battery shell through the core package front-end positioning component and the core package rear-end positioning component, and push out the core package in the shell through the adjustable pushing component; S4: After the pushed-out core package is position-adjusted, it is transferred to the core package transfer machine table. At this time, if there are multiple layers of core packages, the outer film between the multiple layers of core packages is punctured through the transfer manipulator clamping the core package and the separating member to separate the core packages. If the core package is single-layer, it directly enters the area of the orientation adjusting frame. S5: If the starting position of the diaphragm of the core package entering the orientation adjusting frame is incorrect, it is necessary to reverse the direction of the core package or turn the core package over through the core package turning structure and the core package turning-over structure. If the starting position of the diaphragm of the core package already meets the separation requirements, it directly enters the separation module. S6: The core package before entering the separation module is first cut open on the outer layer of the core package, and then the top surface of the core package is separated. The core package is moved to the material distribution table by the crane structure, and then the core package is moved to any work station by the clamping structure of the core package. The negative electrode and the diaphragm of the core package are separated by the upper guide separation device and the lower separation device respectively. The separated negative electrode falls into the negative electrode bin, and the separated positive electrode and diaphragm enter the shearing structure after being guided by the guide roller group and are sheared into blocks. The separated negative electrode, diaphragm and positive electrode all enter the collecting bin.

[0016] The beneficial effects of the present invention are: In the existing battery voltage discharge detection structure, although automatic transmission is performed, the detection terminal still often fails to correspond to the battery pole. Therefore, the present invention sets a limit guide structure on the transmission frame. After the battery is abutted against the limit guide structure through the transmission frame, the position of the battery is guided and fixed by the limit guide structure until the detection terminal on the limit guide structure can connect with the battery pole, so that the detector can accurately judge whether the battery is fully discharged based on the information detected by the detection terminal, and the detected information has a high accuracy.

[0017] After the battery inspection is completed, the batteries that meet the requirements need to be transferred to the next workstation, while the batteries that do not meet the requirements need to be recycled and reprocessed. In order to improve the fluency of battery processing on the production line, the present invention sets a screening structure at the unloading position of the transmission rack. The screening structure is electrically connected to the detector, so that it can determine whether to enable the screening structure based on the battery status detected by the detector, thereby ensuring that the batteries flowing into the next processing station are all fully discharged batteries.

[0018] During the process of cutting the battery, it needs to be moved between different workstations. However, due to the different sizes of batteries of different specifications and manufacturers, the transportation structure needs to be able to be adjusted according to the size of the battery during the movement of the battery. Therefore, the clamping parts provided in the present invention can adjust the size of the opening thereof when the mobile frame moves along the guide frame to the upper end of the battery, so as to adapt to the sizes of different batteries. Therefore, the battery can be in a relatively stable state during the transportation process and is not easy to fall off.

[0019] When cutting batteries, it is generally necessary to go from the inspection station to the cutting station and then to the second cutting station. If it is continuously circulated through only one clamp, its turnover efficiency is very low. Therefore, the present invention sets a first toggle member and a second toggle member at the lower end of the movable frame on the basis of the clamp. In the process of the movable frame driving the clamp to move, the first toggle member and the second toggle member will also be moved accordingly, and at the same time drive the battery on its side to move forward. Therefore, only one set of power is needed to drive the batteries on three stations to move at the same time, which greatly reduces the components of the transfer device, so that the overall structure can be more compact and occupy a smaller area.

[0020] In the existing positioning structure of the battery cutting device, the positioning structure is usually arranged around the cutting structure, which may easily cause the rear end of the battery to warp or swing during the cutting process. Therefore, the present invention first uses a first positioning structure to position and fix the front end of the battery cutting point, and also arranges a second positioning structure in the opposite direction of the first positioning structure, so that the rear end of the battery can also be positioned and fixed, thereby achieving fixation at two points in front and behind the battery, and then achieving a stable positioning effect during the cutting process of the first cutting piece. At the same time, the adjustment of the lateral positioning adjustment piece can also enable the second positioning structure to adapt to the size of the battery. Even when cutting a small battery, the second positioning structure can be moved to the corresponding position through the lateral positioning adjustment piece. It has strong adaptability and can accurately and multi-point position the battery.

[0021] The prior art will push out the membrane of the core package together with the core package when pushing out the core package, so that the membrane is still covered on the outside of the core package, and a separate processing step is required. Therefore, the present invention cooperates with the core package front end positioning component and the core package rear end positioning component. When the battery shell is pressed at both ends, the membrane clamping part is hooked on the inner wall of the battery shell at the same time, so that the membrane can be retained in the shell when the core package is pushed out, which is convenient for subsequent processing.

[0022] When dealing with batteries of different specifications, after detecting the specifications of the batteries in advance, the size of the ejection assembly is changed to adapt to batteries of different specifications, and then the size of the core pack can be adapted when the core pack is ejected, so that the core pack will not be damaged when it is completely ejected.

[0023] In summary, the present invention moves the battery by arranging a guide frame and a moving frame on a transfer machine, and arranges a first positioning structure and a second positioning structure on both sides of the guide frame to position and cut the battery shell. The cut battery is directly transported to the tiltable table at the end of the guide frame, and the core package is pushed out by an adjustable pushing component, so that multiple modules can be integrated on a transfer machine, and the structure is compact while ensuring the batch processing efficiency of the battery.

[0024] The existing multi-layer core packages are mostly processed by manual cutting or automatic cutting, and it is difficult to ensure the cutting depth. If it is too light, the adhesive tape cannot be cut, and if it is too heavy, the inner structure of the core package is easily damaged. Therefore, the present invention provides a core package separation component. After the transfer robot drives the core package moving frame to the position of the core package, the core package limiting component is driven by the core package separation driving member to move to the middle of the two layers of core packages, so that the separation member can penetrate into the adhesive tape between the two layers of core packages and pierce the adhesive tape, thereby separating the two layers of core packages without damaging the core packages themselves, thereby improving the separation efficiency.

[0025] During the process of core package alignment, usually two devices are used to perform turning and flipping separately, and the overall structure is very cumbersome. Not only a large number of mechanical structures need to be added, but also many programming and recognition programs are increased. Therefore, for the core package alignment mechanism of the present invention, the core package turning structure and the core package flipping structure are integrated on a two-position moving frame. The core package turning structure and the core package flipping structure use separate first core package longitudinal moving parts and second core package longitudinal moving parts to achieve longitudinal movement. After the core package turning part moves the core package to the correct direction, the core package is then flipped to the correct angle by the flipping table, providing a positioning basis for the subsequent segmentation of the outer film of the core package. Two steps can be achieved simultaneously within the same mechanism, and the core package turning structure and the core package flipping structure can be driven separately or synchronously, with stronger adaptability.

[0026] During the process of separating the pole pieces of the existing semi-dry core package, since the separator is stuck to the pole pieces, it is difficult to separate them even with an air knife. Therefore, with the upper separation guiding structure provided in the present invention, first, the starting pressing part presses on the starting position of the core package, creating a gap between the separator and the pole pieces, which can be better affected by the air knife. Then, at the end of the separation, the upper pressing guiding part and the upper end cleaning part press on and block the tail end grinding part of the core package, so that the negative electrode can be completely separated from the separator and the positive electrode. And during the whole process, under the guidance of the pole piece end guiding part, each part of the core package can be more stable during the separation stage, improving the separation efficiency.

[0027] In the existing situation, the starting part of the separator of some core packages wraps the negative electrode, making it difficult to blow out the negative electrode, so it is necessary to perform separate pre-treatment on the core package in advance, which is rather troublesome. Therefore, in the present invention, first, the separator starting back-blowing part is set to blow up the starting part of the separator, exposing the negative electrode. Then, immediately, the negative electrode stripping part blows the negative electrode backward. After the negative electrode drops into the negative electrode bin, the back-side isolation pressing part abuts against the bottom end of the separator to block the negative electrode, so that the negative electrode can be completely separated from the separator and the positive electrode, making the recycling stage smoother and the separation efficiency higher.

[0028] In the existing situation, some core packages between the guiding structure and the shearing structure are prone to bending, resulting in insufficient tension of the core package part entering the shearing position. Therefore, with the core package separation guiding assembly provided in the present invention, after the core package passes through the guiding roller group, the guiding air knife part can immediately blow the core package downward, making the core package laid on the guiding bearing plate. At the same time, the core package separation pressing structure is pushed out to press the core package on the guiding bearing plate, so that the starting position of the core package becomes straight, and the continuously incoming core packages are always output straight under the guidance of the guiding air knife part and the guiding bearing plate.

A turning table 57 is arranged on one side of the core package transfer machine table 60 close to the core package translation member 56; A separation module 100, the separation module 100 communicates with a collecting bin 200. The inside of the separation module 100 includes an upper guiding separation device, a lower separation device, and a guiding structure.

The core package separation guiding component includes a guiding air knife member 92 arranged in the direction away from the feeding side of the guiding roller group 91. A guiding bearing plate 93 is arranged at the position where the guiding air knife member 92 is connected to the separation guiding gantry 90 below. A core package separation pressing structure 94 is also arranged on one side of the separation guiding gantry 90 close to the guiding bearing plate 93.

[0076] In the existing structure for detecting the discharge of battery voltage, although there is automatic transmission, the situation where the detection terminal 13 cannot correspond to the battery terminal still often occurs. Therefore, in the present invention, a limit guiding structure is provided on the transmission rack 11. After the battery reaches the limit guiding structure through the transmission rack 11, the position of the battery is guided and fixed by the limit guiding structure until the detection terminal 13 on the limit guiding structure can be connected to the terminal of the battery, so that the detector 14 can accurately judge whether the battery is completely discharged according to the information detected by the detection terminal 13, and the accuracy of the detected information is relatively high.

[0077] During the process of limiting and guiding the battery, it is divided into two parts. Specifically, the limit guiding structure includes a lateral guiding component 121 and a forward guiding component 122 locked on the frame of the transmission rack 11. After the battery transmitted by the transmission rack 11 moves to fit the forward guiding component 122, the lateral guiding component 121 clamps and fixes the battery, and the forward guiding component 122 limits the moving direction of the battery. After the forward guiding component 122 abuts against the battery, the lateral guiding component 121 further limits the battery laterally to ensure that the battery is in place.

[0078] During the limiting process of the forward guiding component 122, the forward guiding component 122 includes a gantry 1221 arranged on the frame of the transmission rack 11. A vertically downward vertical push rod 1222 is installed on the gantry 1221, and a forward baffle 1223 is arranged at the output end of the vertical push rod 1222. When limiting is required, the forward baffle 1223 is pushed out by the vertical push rod 1222, and when limiting is not required, the forward baffle 1223 rises to give way to the battery.

[0079] During the limiting process of the lateral guiding component 121, the lateral guiding component 121 includes a support rod 1211 arranged on the side of the transmission rack 11. An installation plate 1212 is connected between the support rod 1211 and the forward guiding component 122. An inward horizontal push rod 1213 is arranged on the installation plate 1212, and a detection terminal 13 is arranged on the horizontal push rod 1213. After the battery is blocked by the forward baffle 1223, the detection terminal 13 is pushed out by the horizontal push rod 1213 to connect the detection terminal 13 to the terminal of the battery. In this embodiment, the detection terminal 13 is installed on a wire mesh plate, and actually it can also be installed on any other structure connected to the horizontal push rod 1213.

[0080] After the battery is detected, the qualified batteries need to be transferred to the next station, while the unqualified batteries need to be recycled and reprocessed. In order to improve the fluency of the production line in processing batteries, the present invention sets a screening structure at the blanking position of the transfer rack 11. The screening structure is electrically connected to the detector 14, so as to determine whether the screening structure is enabled according to the battery state detected by the detector 14, ensuring that the batteries flowing into the next processing station are all fully discharged batteries.

[0081] Specifically, the screening structure includes a receiving platform 151 located at the blanking position of the transfer rack 11. The receiving platform 151 rotates through a driving structure 152, and the driving structure 152 is electrically connected to the detector 14. When the detector 14 determines that the battery is not fully discharged, the driving structure 152 drives the receiving platform 151 to act. In this embodiment, the discharging method of the receiving platform 151 is flipping, which can be flipped as a whole or only the flipping plate in the middle can be flipped.

[0082] In this embodiment, the driving structure 152 includes a first hinge end 1521 arranged on the adjacent mounting surface and a second hinge end 1522 arranged at the bottom of the receiving platform 151. A blanking push rod 1523 is connected between the first hinge end 1521 and the second hinge end 1522, and the blanking push rod 1523 is electrically connected to the detector 14. Through the hinged connection at both ends, the receiving platform 151 can be flipped.

[0083] During the process of the battery moving from the transfer rack 11 to the receiving platform 151, it can be interfered by an external manipulator or a self-set structure can be used. In this embodiment, a transfer structure 16 is arranged on the side of the limit guiding structure away from the battery feeding direction. The transfer structure 16 includes a guide rail 161 at the end of the transfer rack 11. A translation member 162 is slidably mounted on the guide rail 161. A pushing member 163 is connected to the side of the translation member 162 close to the incoming material direction. When the translation member 162 translates, it drives the pushing member 163 to move horizontally left and right, so that the battery can be pushed onto the receiving platform 151 by the pushing member 163 when the battery is in the stage of the transfer rack 11.

[0084] In order to ensure the stability of the battery on the path from the transfer rack 11 to the receiving platform 151, the pushing member 163 includes an L-shaped baffle 1631 connected to the translation member 162. A pushing plate 1632 is connected to the L-shaped baffle 1631. The pushing plate 1632 and the L-shaped baffle 1631 form an L-shaped structure. Through the transfer method of the L-shaped structure, the battery is not prone to displacement or rotation during the transfer process.

[0085] During the battery voltage detection process, the battery is transferred to the transmission rack 11 by a manipulator, and moved to the position of the limiting guide structure by the transmission rack 11. The battery is first blocked by the forward baffle 1223, and then the two sides of the battery are clamped by the transverse push rod 1213, so that the detection terminal 13 is connected to the battery pole. The battery is detected by the detector 14, and then the transverse push rod 1213 retracts, the forward baffle 1223 rises, and the battery continues to move forward to the position of the push member 163. The battery is moved to the accommodating platform 151 under the drive of the translation member 162. If the detector 14 detects that the battery is completely discharged, it waits for the movement of the next workstation. If the battery is not completely discharged, the blanking push rod 1523 in the driving structure 152 retracts, so that the battery falls along the inclined accommodating platform 151 and is recovered to the front end position.

[0086] During the process of cutting the battery, it needs to be moved between different workstations. However, due to the different sizes of batteries of different specifications and manufacturers, the transportation structure needs to be able to be adjusted according to the size of the battery during the movement of the battery. Therefore, the clamping part 231 provided in this embodiment can adjust its own opening size when the mobile frame 22 moves to the upper end of the battery along the guide frame 21, so as to adapt to the size of different batteries. Therefore, the battery can be in a relatively stable state during the transportation process and is not easy to fall.

[0087] When cutting batteries, it is generally necessary to go from the inspection station to the cutting station and then to the second cutting station. If only one clamping member 231 is used to continuously circulate, its turnover efficiency is very low. Therefore, in this embodiment, a first toggle member 232 and a second toggle member 233 are set at the lower end of the movable frame 22 on the basis of the clamping member 231. In the process of the movable frame 22 driving the clamping member 231 to move, the first toggle member 232 and the second toggle member 233 will also be moved accordingly, and at the same time drive the batteries on its side to move forward. Therefore, only one set of power is needed to drive the batteries on three stations to move at the same time, which greatly reduces the components of the transfer device, so that the overall structure can be more compact and occupy a smaller area.

[0088] During the transportation of the battery, it first needs to move from the voltage detection station to the rest station, and this part is achieved by the movement of the mobile frame 22 on the guide frame 21. Therefore, the guide frame 21 needs to guide the movement direction of the limited mobile frame 22. The guide frame 21 includes a lifting frame 211 for increasing the height. A transverse guide plate 212 is installed on the lifting frame 211. At least two transverse guide rails 213 are locked on the inner side of the transverse guide plate 212. One end of the transverse guide plate 212 is connected to an axial output member 214. The mobile frame 22 is slidably installed on the transverse guide rail 213, so that the mobile frame 22 can move laterally along the transverse guide rail 213.

[0089] The power of the mobile frame 22 is installed on the transverse guide plate 212. In the present embodiment, the axial output member 214 includes a transverse drive motor 2141 locked on one side of the transverse guide plate 212. The transverse drive motor 2141 is connected to a transverse drive screw rod 2142. The transverse drive screw rod 2142 cooperates with the mobile frame 22 through a slider, thereby realizing the transverse movement of the mobile frame 22 by cooperating with the transverse drive screw rod 2142 and the slider. In other embodiments, other driving methods may also be used.

[0090] In the setting process of the traditional moving frame 22, most of the time, only a liftable motor is set on the transverse moving structure to complete the overall deployment. However, in this embodiment, the moving frame 22 includes a transverse moving plate 221 that cooperates with the transverse guide rail 213, and the transverse moving plate 221 is provided with a lower moving push rod 222 and a longitudinal guide block 223. The output end of the lower moving push rod 222 is connected to a longitudinal moving plate 224, and the longitudinal moving plate 224 is slidably connected to the longitudinal guide block 223. An extension plate 225 is set at the bottom of the longitudinal guide block 223, and the clamping part 231 and the toggle assembly are arranged below the extension plate 225, so that the effects of transverse movement, longitudinal movement, and transverse multi-workpiece adjustment can be achieved simultaneously.

[0091] The clamping member 231 is the first step of clamping. Specifically, the clamping member 231 includes a fixed clamping plate 2311 arranged on one side of the bottom surface of the extension plate 225, and a movable clamping plate 2312 slidably connected to the extension plate 225 is arranged on the opposite side of the fixed clamping plate 2311. The movable clamping plate 2312 is driven by a transverse cylinder 2313. The distance between the fixed clamping plate 2311 and the movable clamping plate 2312 is adjustable so that the transfer device can adapt to batteries of most specifications, thereby improving the adaptability of the device.

[0092] In the present embodiment, since there are multiple workstations, in order to adapt to the multiple workstations, the toggle assembly includes a first toggle member 232 and a second toggle member 233. The first toggle member 232 and the second toggle member 233 have the same structure and are arranged in opposite directions. The first toggle member 232 includes a middle locking frame 2321 fixed at the middle position of the bottom of the extension plate 225, and a toggle cylinder 2322 is locked below the middle locking frame 2321. A toggle plate 2323 is arranged on the output end of the toggle cylinder 2322. In fact, different numbers of toggle members can be added according to the number of workstations. The longest and shortest toggle plates 2323 can adapt to batteries of the largest and smallest specifications.

[0093] There is a certain distance between the two toggles. If the battery located there cannot be individually guided and limited, it is prone to offset. Therefore, a lower extension rail 2251 is provided at the bottom of the extension plate 225 in this embodiment. A middle clamping member 234 located between the first toggle 232 and the second toggle 233 is slidably mounted on the lower extension rail 2251. The middle clamping member 234 is connected to the toggle cylinder 2322 through an extension rod 235. When the toggle cylinder 2322 is pushed out, the distance between the middle clamping member 234 and the first toggle 232 becomes longer. The independently provided middle clamping member 234 can achieve adaptive changes in its own position without the need to separately provide a power member, thereby improving the invention of this case without increasing components and circuits.

[0094] In this embodiment, the middle clamping member 234 includes a middle moving seat 2341 slidably connected to the lower extension rail 2251. An auxiliary toggle cylinder 2342 is locked on one side of the middle moving seat 2341. An auxiliary plate 2343 is connected to the output end of the auxiliary toggle cylinder 2342. When encountering a battery with a smaller specification, the auxiliary plate 2343 can be extended to the longest, so as to ensure that the small battery can also be clamped by the middle clamping member 234.

[0095] In the positioning structure of the existing battery cutting device, the positioning structure is usually arranged around the cutting structure, which easily causes the phenomenon that the rear end of the battery warps or swings during the cutting process. Therefore, the present invention first fixes the front end through the first positioning structure 31 at the front end of the battery cutting point, and a second positioning structure 32 is also arranged in the opposite direction of the first positioning structure 31, so as to be able to fix the rear end of the battery, thereby realizing the fixation at two positions, the front and the rear, of the battery, and further achieving a stable positioning effect during the cutting process of the first cutting member 312. At the same time, the adjustment of the lateral positioning adjustment member 321 can enable the second positioning structure 32 to adapt to the size of the battery. Even when cutting a small battery, the second positioning structure 32 can be moved to the corresponding position through the lateral positioning adjustment member 321, with strong adaptability and the ability to accurately position the battery at multiple points.

[0096] In this embodiment, the first positioning structure 31 and the second positioning structure 32 are used to cut off one side of the battery shell. Usually, both sides of the battery shell need to be cut off, so a second group of the first positioning structure 31 and the second positioning structure 32 needs to be set. The first positioning structure 31 and the second positioning structure 32 of the second group are centrosymmetric with the first positioning structure 31 and the second positioning structure 32 of the first group.

[0097] After the battery is transported, due to the different specifications of the batteries, they may not be accurately positioned at the position of the cutting structure. Therefore, a rib groove is provided on the transfer machine table 20 of the present invention. An initial positioning member 33 slidably connected in the rib groove is provided on one side of the second positioning structure 32 close to the battery. When the battery moves to the front end of the first positioning structure 31, the initial positioning member 33 pushes the battery into the first positioning structure 31. Among them, the initial positioning member 33 is an embedded push rod structure, so that the battery can be pushed to the positions of the first cutting member 312 and the first positioning member 311 through the initial positioning member 33 to form an initial positioning.

[0098] After the battery is pushed to the initial position, it is first positioned by the first positioning member 311. Specifically, the first positioning member 311 includes a positioning gantry 3111 provided on the table surface of the transfer machine table 20. A first pressing plate driving member 3112 and a first cutting push rod 3113 are respectively provided on the positioning gantry 3111. A housing pressing frame 3114 is connected to the lower end of the first pressing plate driving member 3112. A cutting knife 3115 is connected to the output end of the first cutting push rod 3113. The housing pressing frame 3114 and the cutting knife 3115 can be respectively driven to act by the first pressing plate driving member 3112 and the first cutting push rod 3113, so that the housing pressing frame 3114 first presses down and then the cutting knife 3115 moves downward.

[0099] Specifically, the housing pressing frame 3114 includes a pressing frame slider 31141 connected to the first pressing plate driving member 3112. The pressing frame slider 31141 is locked on a pressing plate 31142. A reinforcing plate 31143 is locked above the pressing plate 31142. The reinforcing plate 31143 is slidably matched with a positioning frame guide rail 31111 inside the positioning gantry 3111 through a pressing plate slider 31144. When positioning the front end of the battery, the first pressing plate driving member 3112 drives the reinforcing plate 31143 to press down along the positioning frame guide rail 31111, so that the pressing plate 31142 presses the battery tightly.

[0100] The cut battery housing needs to be processed. If it is directly left on the transfer machine 20, it will cause accumulation. Therefore, a housing receiving groove 34 is provided at the lower end of the positioning gantry 3111 in this embodiment. An auxiliary housing positioning member 35 is provided along the side away from the battery on the upper edge of the housing receiving groove 34. When the auxiliary housing positioning member 35 is pushed out, the initial positioning member 33 pushes the battery to fit against the auxiliary housing positioning member 35. The initial positioning member 33 and the auxiliary housing positioning member 35 can form an opposing cooperation. Combining with the first positioning structure 31 and the second positioning structure 32, the battery will be positioned at four points before cutting. And after the outer shell of the battery is cut, not only the cut-off outer shell part will fall into the housing receiving groove 34, but also part of the electrolyte in the housing will flow into the housing receiving groove 34 along the cut. And due to the pressure generated by the second positioning structure 32 at the rear end, the electrolyte at the rear end will also be pressed forward, making it flow out along the direction of the cut, so as to discharge the electrolyte in the battery as much as possible and reduce the difficulty of subsequent processing.

[0101] The position of the second positioning member 322 is not fixed and needs to be changed according to the size of the battery. Specifically, a second positioning frame moving guide 3211 is provided on the lateral positioning adjusting member 321. The second positioning member 322 includes a second positioning slider 3221 that is movably matched with the second positioning frame moving guide 3211. The second positioning slider 3221 is locked on a second positioning plate member 3222. The second positioning plate member 3222 is connected to the lateral positioning screw rod of the lateral positioning adjusting member 321 through a nut, so that the second positioning plate member 3222 can adjust the distance from the first positioning structure 31 according to the size of the battery.

[0102] The second positioning plate member 3222 itself can move in the Z-axis direction. Specifically, the second positioning member 322 further includes a second positioning guide 3223 locked on the second positioning plate member 3222. A second positioning push rod 3224 is locked on the top of the second positioning plate member 3222. The bottom of the second positioning push rod 3224 is connected with an opposite side pressing frame 3225 that is slidably matched with the second positioning guide 3223. The opposite side pressing frame 3225 presses on the rear end of the top surface of the battery, so as to prevent the rear end of the battery from tilting up and laying a good foundation for the next stage of cutting or positioning.

[0103] In order to prevent the battery from being flattened during the battery positioning process, the opposite side pressing frame 3225 includes an opposite side fitting plate 32251 that is matched with the second positioning guide 3223. A reversing block 32252 is locked on the opposite side fitting plate 32251. An opposite side pressing plate 32253 is locked on the reversing block 32252. The opposite side pressing plate 32253 presses on the rear end of the battery, so that the opposite side pressing plate 32253 and the second positioning push rod 3224 are staggered and not in the same straight line, realizing misaligned pressure application.

[0104] In the prior art, when the core package is pushed out, the packaging film of the core package is pushed out at the same time, so that the packaging film still covers the outside of the core package, and a separate processing step is required. Therefore, in the present invention, the front-end positioning component 41 of the core package and the rear-end positioning component 42 of the core package are used in cooperation. During the process of pressing both ends of the battery case, the film clamping member 424 is simultaneously hooked on the inner side wall of the battery case, so that the packaging film can be left in the case when the core package is pushed out, which is convenient for subsequent processing.

[0105] When dealing with batteries of different specifications, after detecting the specifications of the batteries in advance, by changing the size of the pushing component 432, different specifications of batteries can be adapted, and then when the core package is pushed out, the size of the core package can be adapted, and the core package can be completely pushed out without being damaged.

[0106] After the battery case is cut, the core package inside it needs to be pushed out. Before the core package is pushed out, it needs to be fixed. Therefore, in this embodiment, the front-end positioning component 41 of the core package includes a core package positioning gantry 411 fixed on the transfer machine table 20. A core package positioning push rod 412 is arranged on the core package positioning gantry 411. A front core package positioning member 413 is arranged at the bottom end of the core package positioning push rod 412. Before the core package is moved to the pushing station, the core package positioning push rod 412 rises to make way for the battery. After reaching the station, the core package positioning push rod 412 moves down and uses the front core package positioning member 413 as a fixing surface on one side.

[0107] Since the batteries have different sizes, in order to avoid that the battery is too small to be fixed by the front core package positioning member 413, the front core package positioning member 413 in this embodiment includes a core package push rod mounting frame 4131 locked with the core package positioning push rod 412. A core package side push rod 4132 is arranged at the lower end of the core package push rod mounting frame 4131. A core package front baffle 4133 is connected to the output end of the core package side push rod 4132. The core package front baffle 4133 with adjustable position can be used to adapt to small batteries, so as to ensure that the core package can be pushed out.

[0108] In the fixation of the rear end of the core package, the rear-end positioning component 42 of the core package includes a U-shaped guide frame 421 fixed on the transfer machine table 20. A core package pressing push rod 422 is arranged inside the opening of the U-shaped guide frame 421. The core package pressing push rod 422 penetrates through the U-shaped guide frame 421 and a core package rear baffle 423 is connected to the output end. After the core package rear baffle 423 is pushed out, it abuts against the rear end face of the battery case. The surface of the core package rear baffle 423 in contact with the battery is a rough surface, so as to ensure the abutting effect.

[0109] To ensure the retention effect on the envelope without adding unnecessary moving parts, a gap is provided on the side of the core package rear baffle 423. The film clamping member 424 is a hook, which is locked in the gap. In this embodiment, the hook has a certain elasticity, so there is no need to specifically set up a power structure for position conversion.

[0110] To prevent the accidental activation of the core package rear positioning component 42 and the core package front positioning component 41, infrared sensors 44 are provided on the sides of both the core package rear positioning component 42 and the core package front positioning component 41, and they will only be activated when a battery is detected approaching.

[0111] Due to different battery specifications, the opening positions after cutting are also different. To enable the adjustable pushing component 43 to accurately dock with the opening of the battery housing, the adjustable pushing component 43 includes a first adjusting member 433 connected to the transfer machine table 20. The core package power component 431 is movably installed on the first adjusting member 433, so that the core package power component 431 can be aligned with the core package.

[0112] The first adjusting member 433 is a structure that can drive the core package power component 431 to move back and forth. Specifically, the first adjusting member 433 includes a pushing member mounting frame 4331 connected to the transfer machine table 20. A pushing frame guide rail 4332 is provided inside the pushing member mounting frame 4331. A pushing slider 4333 that cooperates with the pushing frame guide rail 4332 is provided at the bottom of the core package power component 431. The core package power component 431 and the pushing member mounting frame 4331 are connected by a worm and worm gear.

[0113] To adapt to battery housings of different heights and widths, the pushing component 432 includes a core package extension rod 4321 connected to the core package power component 431. A number of core package pushing blocks 4322 are locked on the core package extension rod 4321 from bottom to top, and the sizes of the core package pushing blocks 4322 can be installed by themselves at the initial stage.

[0114] After the core package is pushed out, the outer shell needs to be separated and removed separately. In this embodiment, between the core package front positioning component 41 and the core package rear positioning component 42 is an inclined table 45, which can discharge the outer shell for separate recycling and treatment.

[0115] In summary, the present invention moves the battery by providing a guide frame 21 and a moving frame 22 on the transfer machine table 20, and positions and cuts the battery housing by providing a first positioning structure 31 and a second positioning structure 32 on both sides of the guide frame 21. The cut battery is directly transported to the inclined table at the end of the guide frame 21, and the core package is pushed out by the adjustable pushing component 43. Thus, multiple modules can be integrated on one transfer machine table 20, ensuring both a compact structure and the batch processing efficiency of the battery.

[0116] During the processing of partial multi-layer core packs, manual cutting or automatic cutting with a cutting knife is mostly used, making it difficult to ensure the cutting depth. If it is too light, the adhesive tape cannot be cut; if it is too heavy, the inner structure of the core pack is easily damaged. Therefore, in the present invention, through the provided core pack separation component 64, after the transfer manipulator 61 drives the core pack moving frame 62 to move to the position of the core pack, the core pack separation driving component 63 drives the core pack limiting component 641 to move towards the middle of the two-layer core pack, enabling the separating member 642 to penetrate into the adhesive tape between the two-layer core packs, puncturing the adhesive tape, so that the two-layer core packs can be separated without damaging the core pack itself, and the separation efficiency is improved.

[0117] When separating the core pack, since the widths of the core packs of batteries with different specifications are different, the core pack moving frame 62 in this embodiment includes a manipulator connecting frame 621 connected to the transfer manipulator 61. A separation cross frame 622 is connected to the lower end of the manipulator connecting frame 621, and the lower end of the separation cross frame 622 is connected to the core pack separation driving component 63. Through the relatively wide separation cross frame 622, the adjusted-width core pack limiting component 641 can conform to the widths of most core packs on the market, thereby improving the practicality of this case.

[0118] During the process of the core pack separation driving component 63 driving the core pack limiting component 641, since the transfer manipulator 61 will hover above the core pack, if the driving structure is pushed out unidirectionally at this time, secondary position correction is required. Therefore, the core pack separation driving component 63 in this embodiment includes a separation driving motor 631 arranged at the upper end of the separation cross frame 622. The separation driving motor 631 penetrates through the separation cross frame 622 and is connected to a separation driving wheel 632 located at the lower end of the separation cross frame 622. The separation driving wheel 632 is connected to a separation driven wheel through a separation synchronous belt 633. The core pack limiting component 641 is connected to the separation synchronous belt 633. The separating member 642 is a serrated knife, and one side of the serrations of the separating member 642 faces the battery. Through the effect that the two belt surfaces at both ends of the separation synchronous belt 633 move in different directions during operation, the core pack limiting component 641 moves towards the middle or towards both sides simultaneously, and the accurate separation point can be reached with only one-step positioning. Among them, the separation driving motor 631 is a servo motor with extremely high rotation accuracy, so as to accurately control the displacement of the separation synchronous belt 633.

[0119] During the cooperation between the core package limiting component 641 and the separation synchronous belt 633, the core package limiting component 641 includes two groups of core package limiting members. Each core package limiting member includes a limiting connection arm 6411 connected to the separation synchronous belt 633. The limiting connection arm 6411 is connected to a side blocking frame 6412. The lower end of the side blocking frame 6412 is connected to the separating member 642, so that the two side blocking frames 6412 can move synchronously during the movement of the separation synchronous belt 633.

[0120] In this embodiment, the separating member 642 is a serrated knife. One side of the serrations of the separating member 642 faces the battery, and the adhesive tape can be punctured by the serrations during the pushing process of the side blocking frame 6412.

[0121] However, during the process of the separating member 642 puncturing the adhesive tape, the adhesive tape may undergo local movement, which may cause the contact point between the separating member 642 and the adhesive tape to sink inwards, and the separating member 642 cannot puncture the adhesive tape at the preset displacement distance. Therefore, a top core package pressing member 643 is provided inside the side blocking frame 6412 in this embodiment. The top core package pressing member 643 includes a core package top surface pressing push rod 6431 locked on the side blocking frame 6412. The lower end of the core package top surface pressing push rod 6431 is connected with an adhesive tape pressing claw 6432. The adhesive tape on the top surface is fixed by the adhesive tape pressing claw 6432, so that the adhesive tape has sufficient tension when the separating member 642 contacts the adhesive tape and is more easily punctured.

[0122] In order to balance the tension, in this embodiment, the top core package pressing members 643 are located on both sides of one end of the long axis of the separation cross frame 622. There are four top core package pressing members 643 in total. The uniform arrangement can make it easier for the long strip-shaped separating member 642 to separate the adhesive tape.

[0123] The heights and widths of core packages of different specifications are different. Therefore, before processing batteries of the same batch, preset data need to be input so that the transfer manipulator 61 can reach the accurate separation point. In this embodiment, the transfer manipulator 61 includes a manipulator mounting seat 611 connected to the core package transfer machine table 60. A first reversing motor assembly 612 is locked on the manipulator mounting seat 611. One end of the output end of the first reversing motor assembly 612 is connected with a first manipulator stroke extension plate 613. One end of the first manipulator stroke extension plate 613 far away from the first reversing motor assembly 612 is movably connected with a second manipulator stroke extension plate 615 through a second reversing motor assembly 614. One end of the second manipulator stroke extension plate 615 far away from the second reversing motor assembly 614 is provided with a core package separation push rod 616 connected to the manipulator connecting frame 621. By combining the first reversing motor assembly 612 and the second reversing motor assembly 614 with the first manipulator stroke extension plate 613 and the second manipulator stroke extension plate 615, the manipulator connecting frame 621 can reach the accurate position. Whether it is a large core package or a small core package, it is within the stroke range of the transfer manipulator 61.

[0124] In the process of core package alignment, generally two devices are used to carry out rotation and turning over respectively, and the overall structure is very cumbersome. It not only needs to increase a large number of mechanical structures, but also increases many programming and recognition programs. Therefore, for the core package alignment mechanism of the present invention, the core package rotation structure 51 and the core package turning over structure 52 are integrated on a two-position moving frame 59. The core package rotation structure 51 and the core package turning over structure 52 adopt separate first core package longitudinal moving parts 53 and second core package longitudinal moving parts 54 to realize longitudinal movement. After the core package rotator 55 moves the core package to the correct direction, the core package is turned over to the correct angle through the turning table 57, providing a positioning basis for the subsequent division of the outer film of the core package. Two steps can be realized simultaneously within the same mechanism, and the core package rotation structure 51 and the core package turning over structure 52 can be driven separately or synchronously, with stronger adaptability.

[0125] Actually, the core package turning over structure 52 can also move up and down, so as to raise the whole structure during turning over. Due to the limitation of the figure recognition angle, it can be seen that the whole turning table surface 571 cooperates with a guide rail.

[0126] Since the diaphragm openings of some of the core packages are located at the lower end, the entire core package needs to be turned over before the pole pieces are separated. Specifically, the turning table 57 includes a turning table surface 571 connected to the core package transfer machine table 60. An activity groove 572 is provided on the turning table surface 571. Two core package clamping components 573 are slidably connected in the activity groove 572. At one end of the two core package clamping components 573 facing each other, a turning component 574 is movably provided. After the core package clamping components 573 approach each other, they clamp the core package and drive the core package to turn through the turning component 574. That is, the lateral movement is achieved through the core package clamping components 573, and the axial movement is achieved through the turning component 574.

[0127] During the turning process, the turning component 574 includes a turning servo motor 5741 locked in the turning table surface 571. A spline shaft 5742 is connected to the turning servo motor 5741. Both ends of the spline shaft 5742 are connected to a turning driving wheel 5743 through splines. The turning driving wheel 5743 is connected to a turning driven wheel 5745 through a turning synchronous belt 5744. The turning driven wheel 5745 penetrates through the core package clamping component 573 and is connected to a turning clamping part 5746. When the core package clamping component 573 moves, it drives the turning clamping part 5746 to move. The turning servo motor 5741 drives the spline shaft 5742 to rotate, so that the spline shaft 5742 drives the splines to move, and then the turning driving wheel 5743 rotates to drive the turning clamping part 5746 on the driven wheel 5745 to rotate through the turning synchronous belt 5744.

[0128] In order to make the clamping process more stable and make the clamping parts adapt to more models of core packages, the turning clamping part 5746 includes a clamp block 57461 penetrating through the core package clamping component 573. A core package turning frame 57462 is locked on the clamp block 57461. A turning clamping plate 57463 is locked on the core package turning frame 57462. The clamp block 57461 and the turning clamping plate 57463 can be replaced and adjusted according to the core package specifications.

[0129] Before flipping the core package, it is necessary to move the flipping component 574 closer to the core package. Specifically, a holding member guide rail 5711 is provided inside the flipping table 571, and a holding member driving portion 5712 is further provided outside the flipping table 571. The holding member driving portion 5712 is connected to a holding member guiding lead screw 5713 in the direction of the inside of the flipping table 571. The core package holding assembly 573 includes a holding member sliding frame 5731 that is slidably engaged with the holding member guide rail 5711. The holding member sliding frame 5731 is slidably engaged with a spline shaft 5742 through a spline. A holding member slider 5732 of the holding member sliding frame 5731 is engaged with the holding member guiding lead screw 5713. A synchronous belt tension seat 5733 is provided on the top surface of the holding member sliding frame 5731, and the flipping driven wheel 5745 is rotatably mounted on the synchronous belt tension seat 5733. Thus, the holding member guiding lead screw 5713 can be driven by the holding member driving portion 5712, and then the holding member sliding frame 5731 on the holding member guiding lead screw 5713 can slide along the holding member guiding lead screw 5713, and then drive the flipping driven wheel 5745 on the synchronous belt tension seat 5733 to move accordingly.

[0130] When the core package is being turned, it not only needs to move horizontally through the double-position moving frame 59, but also needs to move up and down, so as to be able to approach the core package or make way for the core package. Therefore, the first core package longitudinal moving member 53 in this embodiment includes a first core package longitudinal guiding seat 531 connected to the double-position moving frame 59. A first core package longitudinal moving member 532 is locked at the top of the first core package longitudinal guiding seat 531. The first core package longitudinal moving member 532 passes through the hollow first core package longitudinal guiding seat 531 and is connected to a first core package longitudinal moving frame 533. A core package turning motor 534 is provided on the first core package longitudinal moving frame 533, and the core package turning motor 534 is connected to the core package turning member 55. After the first core package longitudinal moving frame 533 reaches a predetermined height, the core package turning member 55 is then driven to rotate by the core package turning motor 534.

[0131] In order to be able to clamp core packages of different specifications during the adjustment of the core package, therefore, the core package turning member 55 and the core package translation member 56 in this embodiment have the same structure. The core package turning member 55 includes a turning member connecting frame 551. A turning cross frame 552 is connected to the lower end of the turning member connecting frame 551. The lower end of the turning cross frame 552 is connected to a turning driving member 553. Through the relatively wide turning cross frame 552, the turning limit assembly 5534 after adjusting the width can conform to the widths of most core packages on the market, thereby improving the practicability of this case.

[0132] During the process of the steering drive member 553 driving the steering limit assembly 5534, if the drive structure is unidirectionally pushed out at this time, secondary position correction is required. Therefore, the steering drive member 553 in this embodiment includes a steering drive motor 5531 disposed at the upper end of the steering cross frame 552. The steering drive motor 5531 penetrates through the steering cross frame 552 and is connected to a steering drive wheel 5532 located at the lower end of the steering cross frame 552. The steering drive wheel 5532 is connected to a steering driven wheel through a steering synchronous belt 5533. The steering synchronous belt 5533 is connected to a steering limit assembly 5534. Through the effect that the two belt surfaces of the steering synchronous belt 5533 move in different directions during operation, the steering limit assembly 5534 moves towards the middle or towards both sides simultaneously, and the accurate separation point can be reached with just one-step positioning. Among them, the steering drive motor 5531 is a servo motor with extremely high rotation accuracy, so as to accurately control the displacement of the steering synchronous belt 5533.

[0133] During the cooperation between the steering synchronous belt 5533 and the steering limit assembly 5534, the steering limit assembly 5534 includes two sets of core wrapping steering members. The core wrapping steering member includes a steering connecting arm 55341 connected to the steering synchronous belt 5533. The bottom of the steering connecting arm 55341 is connected to a steering bearing frame 55342, and the two steering bearing frames 55342 can move synchronously during the movement of the steering synchronous belt 5533.

[0134] During the process of moving the core package, in order to keep the core package stable, a core package steering pressing member 554 is disposed inside the steering bearing frame 55342. The core package steering pressing member 554 includes a core package steering pressing push rod 5541 locked on the steering bearing frame 55342. The lower end of the core package steering pressing push rod 5541 is connected to a steering pressing claw 5542, and the core package is firmly pressed by the steering pressing claw 5542.

[0135] When the pole pieces are separated, it is divided into three parts, namely the upper guiding separation device, the lower separation device, and the guiding structure. And the upper guiding separation device, the lower separation device, and the guiding structure are provided with two sets of symmetric working stations. When the external manipulator clamps the core package to the middle material distribution table, the core package is moved to any working station through the clamping structure of the core package and the pole pieces are separated. The separated negative electrode falls into the negative electrode recovery transmission frame, and the separated positive electrode and separator fall into the positive electrode recovery transmission frame after being sheared by the shearing structure.

[0136] During the process of separating the electrode sheets from the semi-dry core package, since the separator adheres to the electrode sheets, it is difficult to separate them even with an air knife. Therefore, in the present invention, through the upper separation guiding structure provided, firstly, the starting pressing member 75 presses on the starting position of the core package, creating a gap between the separator and the electrode sheets, which can be better affected by the air knife. Then, at the end of the separation, the upper pressing guiding member 74 and the upper end cleaning member 76 press on and block the end grinding part of the core package, enabling the negative electrode to be completely separated from the separator and the positive electrode. Moreover, during the whole process, under the guidance of the electrode sheet end guiding member 77, each part of the core package can be more stable during the separation stage, improving the separation efficiency.

[0137] In this embodiment, the positions of the upper end post-stripping member 73, the upper pressing guiding member 74, the starting pressing member 75, the upper end cleaning member 76, and the electrode sheet end guiding member 77 on the separation guiding rod 71 are all adjusted manually according to the size of the processed core package. In other embodiments, an electric adjustment method can also be used, which is more precise but requires increasing the cost of the equipment.

[0138] In the later stage of core package separation, the negative electrode needs to be completely separated from the positive electrode and the separator. It is easy for some tails of the negative electrode to be carried to the front position. Therefore, the upper end post-stripping member 73 in this embodiment includes a first movable socket 731 slidably connected to the separation guiding rod 71. The first movable socket 731 is movably connected to the separation guiding rod 71 through a locking member. The lower ends of the two first movable sockets 731 are connected to an upper end stripping frame 732. The inner side of the upper end stripping frame 732 is connected to an upper stripping air knife 733. The lower end post-stripping member 83 includes at least one post-stripping mounting rod 831. A post-stripping air knife 832 is mounted on the post-stripping mounting rod 831. The tapered upper stripping air knife 733 and the post-stripping air knife 832 can form a blowing force and also provide a certain pressing force, making the separation effect of the end negative electrode better. In order to improve the adaptability of the post-stripping air knife 832, the post-stripping mounting rod 831 is mounted on a post-stripping push rod 833, and the post-stripping push rod 833 is mounted inside the negative electrode bin 80, so that the position of the post-stripping air knife 832 can be adjusted.

[0139] During the core package feeding process, the upper pressing guide 74, the starting pressing part 75, the upper end cleaning part 76, and the pole piece end guide 77 need to make way for the feeding structure of the core package. After the feeding is completed, the upper pressing guide 74, the starting pressing part 75, the upper end cleaning part 76, and the pole piece end guide 77 need to lower their heights through the upper guide driving part 78 to contact the core package. Therefore, the upper guide driving part 78 of this embodiment includes two second movable socket seats 781 sleeved on the separating guide rod 71. A separating guide cross plate 782 is locked between the two second movable socket seats 781. A guide separating driving part 783 is locked on the separating guide cross plate 782. The guide separating driving parts 783 at different positions are respectively connected to the upper pressing guide 74, the starting pressing part 75, the upper end cleaning part 76, and the pole piece end guide 77. The upper pressing guide 74, the starting pressing part 75, the upper end cleaning part 76, and the pole piece end guide 77 are all connected to a linear guide frame 784, and the up and down positions can be changed to adapt to different working conditions.

[0140] In order to make the upper pressing guide 74, the starting pressing part 75, the upper end cleaning part 76, and the pole piece end guide 77 more stable during the up and down movement, the linear guide frame 784 includes a linear guide sleeve 7841 locked on the separating guide cross plate 782. The top of a linear guide rod 7842 is movably installed inside the linear guide sleeve 7841 and extends and is fixed to the upper pressing guide 74, the starting pressing part 75, the upper end cleaning part 76, and the pole piece end guide 77. The tops of the two linear guide rods 7842 are both connected to a special-shaped synchronous moving plate 7843. Among them, the middle part of the special-shaped synchronous moving plate 7843 is concave toward the side of the guide separating driving part 783, so the stability is stronger.

[0141] During the pressing process of the upper pressing guide 74, its height does not need to be adjusted. Therefore, the lower end of the upper pressing guide 74 of this embodiment is provided with an upper pressing guide frame 741 connected to the bottom output end of the guide separating driving part 783. The two ends of the top surface of the upper pressing guide frame 741 are connected to the linear guide rod 7842. An upper pressing guide roller 742 is arranged inside the upper pressing guide frame 741, and the pole piece is pressed through the upper pressing guide roller 742.

[0142] When the pole piece clamping structure clamps and approaches the pole piece, the starting pressing part 75 includes a starting connecting plate 751 connected to the linear guide rod 7842 and the guide separating driving part 783. A pressing cone plate 752 is connected to the lower end of the starting connecting plate 751. The starting position of the diaphragm is pressed through the pressing cone plate 752, so that the folded diaphragm can be slightly warped, so that the air knife has a cutting inlet.

[0143] If part of the negative electrode at the end does not completely fall into its recyclable position, in this embodiment, the upper cleaning member 76 includes an upper cleaning guide frame 761 connected to the linear guide rod 7842 and the guide separation driving member 783. A cleaning air knife 762 is locked inside the upper cleaning member 76. The negative electrode that has not been completely recycled can be blown into its recycling end through the cleaning air knife 762 to achieve the cleaning operation of the negative electrode.

[0144] Due to the interference of the pole piece strip structure and the upper pressing guide member 74, the starting pressing member 75, the upper cleaning member 76, and the pole piece end guide member 77, the pole piece may be skewed, affecting the recycling effect. Therefore, in this embodiment, the pole piece end guide member 77 includes a pole piece guide seat 771 provided at the lower ends of the linear guide rod 7842 and the guide separation driving member 783. A U-shaped seat 772 is provided at the lower end of the pole piece guide seat 771. The pole piece moves to the next station through the U-shaped seat 772, and the transmission direction of the pole piece is regulated by the U-shaped seat 772.

[0145] To facilitate feeding, the U-shaped seat 772 includes an upper hollow hopper 7721 connected to the pole piece guide seat 771. Two pole piece guide plates 7722 are connected to the lower end of the upper hollow hopper 7721. The pole piece guide plates 7722 are chamfered along the direction of pole piece transmission, so as to guide the transmission direction of the pole piece.

[0146] In some cases, the starting part of the separator of the core package will wrap the negative electrode, making it difficult to blow out the negative electrode. Therefore, it is necessary to perform separate pretreatment on the core package in advance, which is rather troublesome. Therefore, in the present invention, first, the separator starting part back-blowing member 82 is provided to blow up the starting part of the separator, exposing the negative electrode. Subsequently, immediately, the negative electrode stripping member 84 blows the negative electrode backward. After the negative electrode falls into the negative electrode bin 80, the back-side isolation pressing member 81 abuts against the bottom end of the separator to block the negative electrode, so that the negative electrode can be completely separated from the separator and the positive electrode, making the recycling stage smoother and the separation efficiency higher.

[0147] In some existing core packages, the starting part of the separator will wrap the negative electrode, making it difficult to blow out the negative electrode. Therefore, it is necessary to perform separate pretreatment on the core package in advance, which is rather troublesome. Therefore, in the present invention, first, the separator starting part back-blowing member 82 is provided to blow up the starting part of the separator, exposing the negative electrode. Subsequently, immediately, the negative electrode stripping member 84 blows the negative electrode backward. After the negative electrode falls into the negative electrode bin 80, the back-side isolation pressing member 81 abuts against the bottom end of the separator to block the negative electrode, so that the negative electrode can be completely separated from the separator and the positive electrode, making the recycling stage smoother and the separation efficiency higher.

[0148] After the negative electrode is blown out, in order to prevent the negative electrode from being continuously carried backward during the output process of the positive electrode and the separator, a negative electrode chamber guide rail 801 is provided on the outer side of the negative electrode chamber 80 in this embodiment. The back-side isolation pressing member 81 includes a back-side isolation sliding plate 811 connected to the negative electrode chamber guide rail 801. The back-side isolation sliding plate 811 is connected to a back-side isolation moving frame 812. The back-side isolation moving frame 812 is an L-shaped structure. A back-side isolation guide roller 813 is installed at one end of the short axis of the back-side isolation moving frame 812. One end of the long axis of the back-side isolation moving frame 812 is connected to a back-side isolation frame driving member 814. In the initial stage, the back-side isolation sliding plate 811 can be lowered to make way for other structures, and after the negative electrode is separated, the back-side isolation sliding plate 811 can be raised to intercept the negative electrode.

[0149] When starting the separator, the separator starting back-blowing member 82 is arranged at a position opposite to the negative electrode peeling member 84. Specifically, the separator starting back-blowing member 82 includes a separator starting back-blowing frame 821 locked on the inner side wall of the negative electrode chamber 80. A separator starting direction-adjusting frame 822 is locked on the separator starting back-blowing frame 821. A separator starting air knife 823 is movably installed on the separator starting direction-adjusting frame 822, so that the starting part of the separator can be blown up by the reverse setting method.

[0150] After the starting part of the separator is blown up, the boundary between the negative electrode and the separator and the positive electrode becomes relatively obvious. At this time, the negative electrode peeling member 84 can be directly applied to the negative electrode. Specifically, the negative electrode peeling member 84 includes a negative electrode chamber external frame 841 arranged outside the negative electrode chamber 80. An air knife accommodating groove 842 is formed on the negative electrode chamber external frame 841. A negative electrode peeling air knife 843 is arranged in the air knife accommodating groove. The negative electrode can be blown up by the negative electrode peeling air knife 843.

[0151] Since the feeding angles of different core packages may be slightly deviated, resulting in the deviation of the boundary position between the negative electrode and the separator, the negative electrode peeling air knife 843 in this embodiment is hinged in the air knife accommodating groove 842. A plurality of negative electrode air knife push rods 844 are arranged at the bottom of the negative electrode chamber external frame 841. The output end of the negative electrode air knife push rod 844 is connected to the bottom of the negative electrode peeling air knife 843, so that the position of the negative electrode peeling air knife 843 can be adjusted, thereby adapting to different types of core packages.

[0152] The partial core package between the existing guiding structure and the shearing structure is prone to bending, resulting in insufficient tension in the part of the core package entering the shearing position. Therefore, in the present invention, through the set core package separation guiding component, after the core package passes through the guiding roller set 91, the guiding air knife member 92 can immediately blow the core package downward, so that the core package is laid on the guiding bearing plate 93, and at the same time, the core package separation pressing structure 94 is pushed out to press the core package on the guiding bearing plate 93, so that the starting position of the core package becomes straight, and the continuously incoming core package is always output straight under the guidance of the guiding air knife member 92 and the guiding bearing plate 93.

[0153] After the core package is clamped by the initial clamping structure, the power source for its continuous separation and output comes from the guiding roller set 91. Specifically, a moving guiding roller driving member 901 is provided at the top of the separation guiding gantry 90, a moving guiding roller mounting seat 902 is provided at the bottom of the moving guiding roller driving member 901, the top of the moving guiding roller mounting seat 902 is connected to the separation guiding gantry 90 through at least two moving guiding roller limiting rods 903, the guiding roller set 91 includes a moving guiding roller 911 provided inside the moving guiding roller mounting seat 902, and a fixed guiding roller 912 is provided at the bottom inside the separation guiding gantry 90. One side of the fixed guiding roller 912 is driven by a fixed guiding roller driving member 913, so that the moving guiding roller 911 can be lifted when the clamping structure passes, and the moving guiding roller 911 can be lowered when the core package needs to be transported, and the fixed guiding roller driving member 913 is used to drive the fixed guiding roller 912 to provide a backward force.

[0154] The installation position of the guiding air knife member 92 needs to be relatively close to the core package and does not interfere with other structures. Specifically, the guiding air knife member 92 includes a guiding air knife mounting frame 921 locked on the moving guiding roller mounting seat 902, and a guiding air knife 922 is provided at the bottom end of the guiding air knife mounting frame 921, so that the guiding air knife 922 can be lowered to the position closest to the core package along with the moving guiding roller mounting seat 902.

[0155] In order to make the guiding bearing plate 93 better guide the falling position of the core package, the guiding bearing plate 93 is a square plate, and the surface of the guiding bearing plate 93 facing the guiding air knife 922 is a chamfered corner, and the bent position of the core package always adheres to the position of the chamfered corner.

[0156] After the starting position of the core package is blown out, it may be curved or uneven. At this time, if it directly falls into the shearing structure, it may be difficult to perform uniform cutting. Therefore, a side ear seat 904 is provided on the outer side of the separation guiding gantry 90 of this embodiment. The core package separation pressing structure 94 includes a pressing guiding rod 941 locked on the side ear seat 904. A core package separation pressing seat 942 is slidably installed on the pressing guiding rod 941. On the side of the core package separation pressing seat 942 away from the side ear seat 904, there is a core package separation positioning seat 943 slidably connected to the pressing guiding rod 941. A core package separation driving member 944 is installed on the core package separation positioning seat 943. The output end of the core package separation driving member 944 is connected to the core package separation pressing seat 942. The core package separation pressing seat 942 can be pushed out by the core package separation driving member 944 to flatten the starting head of the core package at the position of the guiding bearing plate 93, so that it can fall smoothly and straight.

[0157] Specifically, the core package separation pressing seat 942 includes a core package separation sleeve 9421 sleeved on the pressing guiding rod 941. The core package separation sleeve 9421 is locked on a core package separation synchronous plate 9422. The side of the core package separation synchronous plate 9422 away from the guiding bearing plate 93 is connected to the core package separation driving member 944. A core package separation pressing plate 9423 adapted to the guiding bearing plate 93 is locked on the side of the core package separation synchronous plate 9422 close to the guiding bearing plate 93. The core package separation pressing plate 9423 adapted to the guiding bearing plate 93 can completely cover the core package, thereby ensuring that the entire surface of the core package can be flattened.

[0158] In another embodiment of the present invention, a battery fine disassembly method is also disclosed. Applying the above-mentioned battery fine disassembly system, it includes the following steps: S1: Transport the battery into the detection machine table 10 for discharge detection. The fully discharged battery waits for subsequent processing, and the incompletely discharged battery is transported back to the front-end position; S2: Clamp the fully discharged battery by the clamping member 231 and move it to the position of the first positioning structure 31. Position the battery through the first positioning structure 31 and the second positioning structure 32. Cut off the outer shell on one side of the battery by the first cutting member 312. Similarly, cut off the outer shell on the other side of the battery in the same way to expose the core package of the battery; S3: Fix the cut battery outer shell through the core package front-end positioning component 41 and the core package rear-end positioning component 42, and push out the core package in the outer shell through the adjustable pushing component 43; S4: After the core package is pushed out and its position is adjusted, it is transferred to the core package transfer machine 60. At this time, if there are multiple layers of core packages, the transfer manipulator 61 grabs the core packages and then pierces the outer film between the multiple layers of core packages through the separating member 642 to separate the core packages. If the core package is single-layer, it directly enters the area of the orientation frame 50. S5: If the starting position of the diaphragm of the core package entering the orientation frame 50 is incorrect, the direction of the core package needs to be reversed or the core package needs to be turned over through the core package steering structure 51 and the core package turning-over structure 52. If the starting position of the diaphragm of the core package already meets the separation requirements, it directly enters the separation module 100. S6: Before entering the separation module 100, the core package first cuts the film on the outer layer of the core package, then separates the top surface of the core package. After the core package is moved to the material distribution table by the traveling structure, the core package is moved to any working position through the clamping structure of the core package. The negative electrode and the diaphragm of the core package are separated by the upper guiding separation device and the lower separation device respectively. The separated negative electrode falls into the negative electrode bin 80. After being guided by the guiding roller group 91, the separated positive electrode and diaphragm enter the shearing structure and are cut into blocks. The separated negative electrode, diaphragm, and positive electrode all enter the aggregate bin 200.

[0159] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

10. A battery disassembly method, which is applied to a precise battery disassembly system described in any one of claims 1 to 9, and is characterized in that, The steps are as follows: S1: The battery is conveyed into the detection machine table (10) for discharge detection. The completely discharged battery waits for subsequent processing, and the incompletely discharged battery is conveyed back to the front end position; S2: The completely discharged battery is clamped by the clamping part (231) and moved to the position of the first positioning structure (31). The position of the battery is positioned by the first positioning structure (31) and the second positioning structure (32). One side shell of the battery is cut off by the first cutting part (312). Similarly, the other side shell of the battery is cut off in the same way to expose the core package of the battery; S3: The cut battery shell is fixed by the core package front end positioning component (41) and the core package rear end positioning component (42), and the core package in the shell is pushed out by the adjustable pushing component (43); S4: After the pushed-out core package is adjusted in position, it is transported to the core package transfer machine table (60). At this time, if there are multiple layers of core packages, the outer film between the multiple layers of core packages is punctured by the transfer manipulator (61) clamping the core package and passing through the separating part (642) to separate the core packages. If the core package is single-layer, it directly enters the area of the orientation adjusting frame (50); S5: If the starting position of the diaphragm of the core package entering the orientation adjusting frame (50) is incorrect, the direction of the core package needs to be reversed or the core package needs to be turned over by the core package turning structure (51) and the core package turning-over structure (52). If the starting position of the diaphragm of the core package already meets the separation requirements, it directly enters the separation module (100); S6: Before the core package enters the separation module (100), the film on the outer layer of the core package is first cut, and then the top surface of the core package is separated. After the core package is moved to the material distribution table by the overhead crane structure, the core package is moved to any station through the clamping structure of the core package. The negative electrode and the separator of the core package are separated by the upper guiding separation device and the lower separation device respectively. The separated negative electrode falls into the negative electrode bin (80), and the separated positive electrode and separator enter the shearing structure to be cut into blocks after being guided by the guiding roller group (91). The separated negative electrode, separator, and positive electrode all enter the aggregate bin (200).
